Can you provide a full build log of a clean build?
Sure: https://gist.github.com/certik/5528134 The build was produced by the "build.sh" script, also in the gist. On the line 48 (https://gist.github.com/certik/5528134#file-mpl_log-txt-L48) you can see where our own PNG lib is: [matplotlib] lrwxrwxrwx 1 ondrej cnls 11 May 3 11:48 /auto/nest/nest/u/ondrej/repos/python-hpcmp2/opt/png/qhle/lib/libpng.so -> libpng16.so [matplotlib] lrwxrwxrwx 1 ondrej cnls 18 May 3 11:48 /auto/nest/nest/u/ondrej/repos/python-hpcmp2/opt/png/qhle/lib/libpng16.so -> libpng16.so.16.2.0 as printed by the line 5 in build.sh: echo "Our PNG library:" ls -l $PNG/lib/libpng*.so The actual mpl build starts at the line 52 (https://gist.github.com/certik/5528134#file-mpl_log-txt-L52). As you can see, it found the systemwide PNG lib: [matplotlib] OPTIONAL BACKEND DEPENDENCIES [matplotlib] libpng: 1.2.46 and just to verify this, at the line 2636 (https://gist.github.com/certik/5528134#file-mpl_log-txt-L2636) I print: echo "The linked PNG library:" ldd $PYTHON/lib/python2.7/site-packages/matplotlib/_png.so which gives: [matplotlib] The linked PNG library: [matplotlib] linux-vdso.so.1 => (0x00007fffd8bc1000) [matplotlib] libpng12.so.0 => /lib/x86_64-linux-gnu/libpng12.so.0 (0x00007f1fd0c0a000) [matplotlib] libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f1fd090a000) [matplotlib] libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f1fd06f3000) [matplotlib] libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f1fd04d6000) [matplotlib] libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f1fd0117000) [matplotlib] libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f1fcfeff000) [matplotlib] libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f1fcfc03000) [matplotlib] /lib64/ld-linux-x86-64.so.2 (0x00007f1fd107e000) So the systemwide png /lib/x86_64-linux-gnu/libpng12.so.0 is linked instead: ondrej@kittiwake:~$ ls -l /lib/x86_64-linux-gnu/libpng12.so.0 lrwxrwxrwx 1 root root 18 Apr 5 2012 /lib/x86_64-linux-gnu/libpng12.so.0 -> libpng12.so.0.46.0 as you can see, it is exactly the one as advertised by the mpl build info above. So the mpl build seems consistent, and the bug is that it finds the systemwide version before our own version.
